How do I solve this and please thoroughly explain the steps, please?

Answer: 200

Step-by-step explanation:

since 10 is one part

10 x 20 = 200

The real length of the car will be 200 units.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A scale of 1:20 is used to make the drawing of a car.

And, The length of the drawing is 10.

Now,

Since, The length of the drawing is 10.

And, The used scale = 1 : 20

Hence, The real length of the car = 20 × 10

                                                    = 200 units

Answer:

4 meters

Step-by-step explanation:

Given that :

Initial elevation of butterfly = 20 meter

Change in elevation from initial height = negative 16 m = - 16 meter

Final elevation can be obtained by taking the sum of initial elevation and the change in elevation

(20 m + (- 16 m))

(20 m - 16 m)

= 4 meters

Answer:24

Step-by-step explanation:

Sum of their ages is 60 yr. As such

7x + 3x = 60

10x = 60

x = 60 / 10

x = 6

The rationale is 6, therefore

Father's age is 7x = 7 × 6= 42 years

Son's age is 3x = 3 × 6 = 18 years

Difference in their ages

42 - 18 = 24 years

Answer:

Then the answer to the system is the point (-1, 3)

which corresponds to x = -1 and y = 3

Step-by-step explanation:

Start by dividing the first equation by 3 on both sides, and get:

x + y = 2

now multiply it by 5 in order to be able to eliminate the term in y in the combining of both equations:

5 x + 5 y = 10

+

9 x - 5 y = - 24

___________

14 x + 0 = -14

solve for x by dividing both sides by 14:

x = -14/14 = -1

Use the x = -1 answer in the equation 3 x + 3 y = 6 and solve for y:

-3 + 3 y = 6

add 3 on both sides:

3 y = 9

divide both sides by 3 to isolate y:

y = 3

Then the answer to the system is the point on the plane (-1, 3)

which corresponds to x = -1 and y = 3

Answer:

0.0946km²

Step-by-step explanation

Area of the farmland owned = 0.037km²

Area of farm land bought = 9600m²

Convert m² to km²

1m² = 1e-6 km²

9600m² = 0.000001 * 9600

9600m² = 0.0576km²

Total area on km² = 0.037km²+0.0576km²

Total area on km²  = 0.0946km²

Answer:

37:5

Step-by-step explanation:

Answer:

Here i will simplify 49/7 to its simplest form and convert it to a mixed number if necessary.

In the fraction 49/7, 49 is the numerator and 7 is the denominator.

do this by first finding the greatest common factor of 49 and 7, which is 7.

Then, divide both 49 and 7 by the greatest common factor to get the following simplified fraction:

7/1

Therefore, this equation is true:

49/7 = 7/1

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.

7/1 = 7

Answer:

Amount left in the container is [tex]400\:\text{kg}[/tex].

Step-by-step explanation:

Given: A container holds [tex]600[/tex] kg of rice.  [tex]33 \frac{1}{3} \%[/tex] of rice was distributed to groceries.

To find: How many kilograms of rice remained in the container?

Solution:

We have,

Amount of rice in the container [tex]=600[/tex] kg

Amount distributed to the groceries [tex]=33 \frac{1}{3} \%= \frac{100}{3}\%[/tex]

Therefore, amount distributed to groceries[tex]=\frac{100}{3}\times\frac{1}{100}\times600=200 \:\text{kg}[/tex]

Now, amount of rice left in the container[tex]=600\:\text{kg}-200\:\text{kg}=400\:\text{kg}[/tex]

Hence, amount of rice left in the container is [tex]400 \:\text{kg}[/tex].

Answer:

4.52secs

Step-by-step explanation:

Given the height of a falling object expressed as;

d=3t+5t^2

If the object travel 84 feet, we are to find the time t it takes to travel. On substituting;

84 = 3t+5t^2

3t+5t^2 - 84 = 0

t = -5±√25-4(3)(-84)/2(3)

t = -5±√25+1008/6

t = -5±32.14/6

t = -5+32.14/6

t = 27.14/6

t = 4.52 secs

Hence it will take 4.52secs for the object to travel 84feet

Answer:

False

Step-by-step explanation:

The graph of a linear function is a straight line. Graphically, where the line crosses the x -axis, is called a zero, or root. Algebraically, a zero is an x value at which the function of x is equal to 0 . Linear functions can have none, one, or infinitely many zeros.

Answer:

True.

Step-by-step explanation:

A linear function has the exponent of 0 or 1. A function with a degree of 2 would be quadratic and an exponent of 3 would be cubic.

Answer: 18.29%

Step-by-step explanation:

There are 350 students. Out of these students, 70 signed up for the Army, 64 for the Airforce, 56 for the Navy and 160 for the Marines for a total of 350.

The percentage of students who signed up for the Airforce out of the total can be calculated by:

= number of students (airforce) / total number of students * 100

= 64/350 * 100

= 18.29%

Answer:

The answer is "[tex]\frac{2}{9} \ and \ \frac{1}{9}[/tex]"

Step-by-step explanation:

In point a:

The requires  1 genin, 1 chunin , and 1 jonin to shape a complete team but we all recognize that each nation's team is comprised of 1 genin, 1 chunin, and 1 jonin.

They can now pick 1 genin from a certain matter of national with the value:

[tex]\frac{1}{\binom{3}{1}}=\frac{1}{3} .[/tex]

They can pick 1 Chunin form of the matter of national with the value:

[tex]\frac{1}{\binom{3}{1}}=\frac{1}{3} .[/tex]

They have the option to pick 1 join from of the country team with such a probability: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]

And we can make the country teams: [tex]3! = 6[/tex] different forms. Its chances of choosing a team full in the process described also are:

[tex]6 \times \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}=\frac{2}{9}.[/tex]

In point b:

In this scenario, one of the 3 professional sides can either choose 3 genins or 3 chunines or 3 joniners. So, that we can form three groups that contain the same ninjas (either 3 genin or 3 chunin or 3 jonin).

Its likelihood that even a specific nation team ninja would be chosen is now: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]

Its odds of choosing the same rank ninja in such a different country team are: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]

The likelihood of choosing the same level Ninja from the residual matter of national is: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex] Therefore, all 3 selected ninjas are likely the same grade: [tex]3\times \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}=\frac{1}{9}[/tex]

Answer: 10 large melons

Step-by-step explanation:

Carl saw 25 melons at a store.

Of these 25, 15 were small and the rest were large.

The number of large melons will have to be the whole total of 25 melons less the number of small melons which is 15:

= 25 total melons - 15 small melons

= 10 large melons
